Hi just in the process of planning out a new retrofit on a machine as the old control has fell over and the cost of fixing it is very high
long storie short its going to get an upgrade to linuxcnc like the other machines i have now. i am just in the process of picking out the new servo motors as i cant not reuse whats on there currently its been a while since i have had a chance to keep up with current devel of linuxcnc First questoin is i am just wondering what is the current state of using ABS encoders with linuxcnc, is it fully implemented , ie what about when the encoder bat goes flat/postion is lost can you still rehome machine normlay and does linuxcnc know postion is wrong/missing and force a rehome. like other machines i have do. what about multiturn or single turn abs encoder, servo drives i am looking at would have a 17bit ABS 2nd question wondering weather to go with Analog servo drive input or now is the time to move on to ethercat servo drive interface. i like the idea of ethercat more simple wiring etc.i see alot are using the drive in postion mode with ethercat so i guess one needs to tune up the drive well on the drive its self like using PID in linuxcnc just you no longer have a PID in hal any more correct? i guess postion loop becomes as good as having the PID with in hal, throughts on this subject any one? this is on a 5 axis VMC machine with some large servos , more so a Matsuura doign 15m/min rapids rob ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
